LOUIS P. TIERS, OF EVANSTON, ILLINOIS, ASSIGNOR TO PROGTOR & SCHWARTZ, INCOR- POKATED, 0F PHILADELPHIA, PENNSYLVANIA, A CORPORATION 01 PENNSYLVANIA SCORING DEVICE FOR SOAP ROLLS Application filed December 22, 1830. Serial No. 504,135.

This invention relates to scoring devices for use in plastic material treating apparatus. The present invention relates particularly to a scoring device for use with a soap chilling roll, whereby a film of soap, solidifying on the roll, may be scored PIIOI to its removal from the roll, so that the film will be broken up into flakes of substantially uniform size and shape as it is scraped off the face of the roll.

Scorin devices have been employed in the past for marking the film along substantially straight parallel lines running circumferentially of the face of thechilling roll, to divide the film into ribbons of predetermined widths. As these ribbons are subsequently scraped from the face of the roll the soap breaks up into flakes of various unequal s1zes.

One object of this invention is to score the soap film by providing parallel undulated or zig-zag scorings in the film on the face of the roll, so that as the film is scraped from the face ofthe roll it will break up into flakes of substantially uniform size, as determined by the changes in direction of the undulations.

Another object of the invention is to provide a plurality of scoring elements arranged in two separate but parallel series, the respective series being actuated in such a manner that the scorings made by one series will intersect the scorings made by the other series, producing flakes of predetermined uniform shape and size.

The construction and operation of the device will be fully disclosed hereinafter, ref erence being had to the accompanying drawing, of which;

Figure 1 is an elevation of a soap chilling roll, showing the improved scoring device operating on the face of the roll;

Fig. 2 isa sectional elevation taken on the line 2-2, Fig. 1; and

Fig. 3 is a diagrammatic view showing one form of the intersecting scorings adapted to produce flakes of a predetermined shape.

The chilling roll, shown at -1, is provided with a peripheral film carrying face 2 to which the soap is applied in a more or less plastic or semi-liquid state. The soap is formed in a relatively thin film on the face shaft or trunions 4, 4 which are rotatably mounted in suitable bearings, not shown, which are carried by or formed on side frames 5 and 6 respectively.

Any of the well known means may be provided for keeping the roll 1' at a predetermlned temperature calculated to cause the SOiIIP to chill and solidify on the face 2 of the r0 The scraping knife 3 is also carried by the frames 5 and 6 and is adapted to be adjustable relative to the face of the roll 2 to obtain the most eflicient angle relative to the face 2 for scraping the soap from the roll 1.

The scoring device, forming the subject of the present invention comprises a. pair of parallel longitudinally slidable bars 10 and 11 which are 'slidably mounted in the bearings 12 and 13 carried by the frames 5 and 6 respectively.

The bars 10 and 11 are adapted to be recip-- rocated longitudinally across the film carrying face 2 of the chilling roll 1.

The bars 10 and 11 respectively carry series of holders 14 and 15, in which are mounted scoring elements 16 and 17 respectively.

The scoring elements in the present instance are in the form of relatively sharp needles or short wires, the points of which are adapted to bear against the chilling surface 2 of the roll 1, so that as the roll is r0- tated, the scoring elements 16 and 17 will produce grooves or-m'arks in the film of soap carried by the face 2 of the roll 1.

Reciprocation of the bars 10 and 11, and the scoring elements 16 and 17 respectively carried thereby, is effected by a rotary circular cam 20, having a high spot 21 and a low spot 22 diametrically opposed .to the high spot 21, the intervening portions of the cam path being in the form of straight faced inclines 23 extending between the high and low spots 21 and 22 respectively. I

The cam bears a ainst a lug or projection 24 on a head 25 earned on the adjacent ends of the slide bars 10 and 11.

The bars 10 and 11 are further united for simultaneous operation by straps 26 and 27 secured to the slide bars.

The opposite ends of the slide bars 10 and 11 are mounted in bores 28 and 29 formed in the bearing 12 and intermediate the end wall of the bore and the end of the slide bar mounted in the bore, is a sprin 30, which tends at all times to force the sli e bars 10 and 11 to the right as seen in Fig. 1. I

Forcin the slide bars 10 and'11 to the right, as a ve noted, maintains the operating projection 24 of the head 25 in o erative engagement with the" cam 20 at al times, and as the cam 20 is rotated, this cooperative engement efiects longitudinal reciprocation of the bars 10 and 11 and lateral reciprocation of the scoring elements 16 and 17 carried by the bars 10 and 11 respectively.

As shown in Figs. 1 and 3 the lateral movement of the scoring elements 16 and 17 is substantiall equal to the spacing of the elements 16 and 1 on the bars 10 and .11.

The scoring elements 17 are preferably aligned respectively with the scoring. elements 16 in a direction circumferent ally of the roll 1 so that as roll 1 and cam 20 rotate, each aligned pair of scoring elements will move laterally, for exam le to the right, see the bottom of Fig. 3, prodhcing inclined par- 3 allel scorings a and b respectively. As the cam 20 continues to rotate, and the roll 1 also continues to rotate the scoring elements 16 and 17 will move to the left, producing the I inclined parallel scoring lines a and 6 respectively.

It will be here noted that the left inclines 1) formed by the scoring elements 17, intersect and cross the right inclines a, previously formed by the scoring elements 16.

When making the next right inclines b the scoring elements'17 intersect and cross the previously formed left inclines a formed by the scoring elements 16.

This intersecting and crossing of the scor- -ing lines made by each circumferentially aligned pair of scoring elements 16 and 17 respectively continues in this manner throughout the operation of the device.

The reciprocation of the bars 10 and 11 being substantially equal to the spacing of the scoring elements longitudinally of the bars, causes the turning points of the undulations ofthe scored lines made by the scoring elements 16 to adjoin with the turning points of the undulations of the scored lines made by the scoring elements 17, 17 at the opposite sides of the line made by the said scoring element 16, the scoring element 17 of the articular pair 16-17, forming lines whic at their turning oints ad'oin with the turning points of the lines ma e by the scoring elements 16, 16 of the pairs 1617 at each of the opposite sides of theparticular pair first mentioned. i

In this way the entire film F carried on the surface 2 of the roll 1, as it passes the scoring elements 16, 16 and 17,17, is scored or cross hatched in the manner indicated in Fig. 1, dividin the film into uniformdiamond-v shaped %)locks D, D, which are subsequently removed in this form by the scraping knife 3.

The cam 20 is mounted for rotation on a stud carried by the bearing 13, and is provided, in the present instance with a sprocket wheel 36 around which passes a drive chain 3 The drive chain 37 also passes around a sprocket wheel 38 secured to a drive shaft 39, rotatably mounted in bearing (not shown) carried by the frames 5 and 6 respectively.

On the drive shaft 39 is a gear 40 which meshes with a ear 41 carried by one of the trunnions of the chilling roll 1 thus, when power is applied to the drive shaft 39, the chilling roll 1 and the cam 20 are rotated at a predetermined speed ratio.
